Personal Reflection (NEWater visit)

After this trip to NEWater, I've learnt that:
1. Water that enters the plant is first treated in the Water Reclamation Plant.
2. NEWater contributes to the tap water we use after being mixed into the reservoirs and this is known as Indirect Portable Use (IPU)
3. NEWater has to be neutralized after the treatment by sodium hydroxide.
4. Singapore has a contract with Malaysia regarding the water supply which is expiring just next year.
5. Pores or the hollow fibre membrane are 0.04 microns and that of the reverse osmosis system are as low as 0.0001 microns.
6. Singapore consumes about 600 olympic-sized-swimming-pool amount of water daily.
7. The ultraviolet rays are 100 times as powerful as the sun's.

I can help in the water conservation of water in Singapore by:
1. Use water only as needed, eg. Switch off taps when not in use, use basins to wash the dishes.
2. Reuse water, eg. use water which was used to wash rice to water plants, using water from the washing machine to flush the toilet.
3. Promote water conservation to everyone.
